1. What Happens after a Criminal Arrest in San Diego County?
After an arrest, police may keep a suspect in custody or release that person while prosecutors review the allegations. The first steps depend on custody status, the reason for arrest, and whether prosecutors file a complaint.
When Must Someone Appear before a Magistrate?
For an arrested person who remains in custody, California Penal Code § 825 generally requires an appearance before a magistrate without unnecessary delay and within 48 hours of arrest, excluding Sundays and holidays.
The period begins at arrest rather than completion of booking. Court-session exceptions can extend the deadline, while qualifying arrests after Wednesday's court session are subject to a special Friday requirement.
This deadline governs the initial appearance, not a universal deadline for filing criminal charges.
Can Police Release Someone without Filing Charges?
Police may release someone arrested without a warrant instead of bringing that person before a magistrate in circumstances specified by Penal Code § 849(b). These include insufficient grounds for a criminal complaint and certain releases involving treatment or support services.
When release falls under § 849(b)(1), (3), (5), or (6), § 849(c) requires the arrest record to include the release and provides that the arrest is thereafter deemed a detention only. This classification does not necessarily prevent prosecutors from filing charges later.
A citation or release notice should be checked for any required appearance date. An attorney can also examine whether officers had sufficient grounds for a warrantless arrest.
Which Prosecutor Handles the Case?
The San Diego County District Attorney generally prosecutes felonies throughout the county and misdemeanors outside the San Diego City Attorney's jurisdiction. The City Attorney generally prosecutes misdemeanors committed within San Diego city limits.
State criminal proceedings take place in California Superior Court, with criminal divisions serving Central, North County, South County, and East County.
Federal charges follow separate procedures in United States District Court. Federal Rule of Criminal Procedure 5 generally requires an initial appearance without unnecessary delay rather than applying California's § 825 deadline.
2. How Can an Attorney Challenge the Arrest or Evidence?
An arrest does not establish that every police action was lawful. Defense review can examine whether officers had probable cause, whether questioning complied with constitutional requirements, and whether a search violated the Fourth Amendment.
These questions affect the admissibility of evidence, but a constitutional violation does not automatically require dismissal of every charge.
Probable Cause and Police Questioning
Probable cause concerns whether the circumstances provided legally sufficient grounds for an arrest. The prosecution must later satisfy a different standard to obtain a conviction: proof beyond a reasonable doubt.
Under Miranda v. Arizona, warnings generally must precede custodial interrogation when prosecutors seek to introduce resulting statements in their case-in-chief. Both custody and interrogation must be present.
A suspect may invoke the right to remain silent during custodial questioning. The Sixth Amendment right to an attorney attaches after adversarial judicial criminal proceedings begin and follows a separate analysis.
Suppression Motions under Penal Code § 1538.5
Penal Code § 1538.5 permits a defendant to seek suppression of evidence obtained through an unlawful search or seizure. A motion must identify the challenged evidence and explain the grounds for suppression.
San Diego Superior Court Local Rule 3.2.2 imposes additional filing requirements, including the applicable charging document and relevant search-warrant materials. The motion's timing also depends on the procedural stage.
Under Local Rule 3.2.3, the judge sets the felony pretrial-motion filing deadline at 21 calendar days after the post-bindover arraignment on an information or arraignment on an indictment, unless the judge assigns another date for good cause.
Preserving Evidence before Trial
Messages and location records may help establish a timeline, while photographs, recordings, or transaction records may challenge witness accounts or elements of the alleged offense.
Original files and available metadata should be preserved so their authenticity and contents can be examined. An attorney can compare these materials with police reports and witness statements to identify factual inconsistencies.
The rules of criminal evidence determine whether particular materials may be admitted or challenged. Deleting records or coordinating witness accounts can create additional legal problems.
3. Arraignment and Felony Preliminary Hearings
Once prosecutors file charges, the court addresses the defendant's plea, appearance requirements, and subsequent proceedings. Misdemeanor and felony cases follow different procedures, and some defendants must appear personally.
Can an Attorney Appear without the Defendant?
California Penal Code § 977 permits attorney-only appearances in certain misdemeanor proceedings, subject to statutory exceptions and court orders. Domestic violence and specified DUI cases can involve additional personal-appearance requirements.
San Diego Superior Court Local Rule 3.1.2 separately permits qualifying misdemeanor and infraction arraignments at the counter or by fax. An authorized attorney must enter a not-guilty plea and waive trial time with the defendant's authorization.
The local procedure excludes defendants in custody and specified categories involving child abuse, domestic violence, sex-offender registration, certain City Attorney prosecutions, victim appearance rights, and forfeited bail.
Attorneys must also satisfy the court's CRM-140 criteria and CRM-141 form requirements. Eligibility under § 977 does not automatically establish eligibility for the local procedure.
These distinctions affect preparation for an arraignment and bail hearing.
The 10-Day and 60-Day Preliminary Hearing Rules
Felony prosecutions initiated by complaint ordinarily proceed to a preliminary hearing unless the hearing is waived or another lawful procedure applies. The magistrate determines whether sufficient cause exists to hold the defendant to answer.
Under Penal Code § 859b, the hearing generally must occur within 10 court days after the applicable arraignment, plea, or reinstatement date. Statutory waivers and good-cause continuances may affect that period.
Defendants held solely on the complaint receive additional protections against prolonged detention. The consequences of missing the 10-day deadline depend on the statutory custody conditions and exceptions.
A separate 60-calendar-day limit generally applies. Extending the hearing beyond that limit requires the defendant's personal waiver; good cause alone does not create an exception.
A violation requires dismissal of the complaint under the applicable statutory rule, but dismissal does not necessarily prohibit a later prosecution.
In Mendoza v. Superior Court (California Court of Appeal, 2025), the court held that arraignment on an amended complaint does not restart the 60-day period when the defendant did not personally waive the original limit. The court dismissed the writ petition as moot after addressing the legal question.
4. Building a Defense before Trial
Defense preparation focuses on the offenses actually charged and the evidence prosecutors intend to use. An attorney can examine whether the alleged conduct satisfies each statutory element and whether witnesses or records support a competing account.
Reviewing the Elements of Each Charge
The prosecution must establish the elements of the particular offense charged, including any required mental state. For example, a theft allegation under California Penal Code § 484 requires proof of the applicable theft theory and intent, not merely evidence that property changed hands.
For misdemeanor defense or felony defense, an attorney can compare the allegations with the governing statute and identify facts that support or dispute the prosecution's theory.
Discovery and Witness Evidence
Penal Code § 1054.1 requires prosecutors to disclose specified information to the defense, subject to statutory conditions. Covered materials include certain witness information, defendant statements, and relevant evidence.
Under § 1054.7, required disclosures generally must occur at least 30 days before trial. Information discovered within that period ordinarily requires immediate disclosure.
A court may restrict, defer, or deny disclosure only upon good cause within the statute's defined grounds. These deadlines relate to trial preparation, not the original arrest date.
Reviewing discovery can reveal inconsistent accounts, disputed identification, or missing records. Those issues may affect motions, negotiations, and trial preparation without determining the outcome in advance.
5. Criminal Defense Representation after an Arrest
A criminal defense attorney can review arrest reports, charging documents, witness statements, and available evidence to identify potential defenses and procedural issues. The review may also address custody status, release conditions, and upcoming court deadlines.
Defense preparation may involve examining constitutional violations, challenging particular evidence, or preparing for arraignment and a felony preliminary hearing. The available options depend on the charges, procedural stage, and case records.
SJKP LLP can evaluate the applicable California criminal procedures, prepare for upcoming hearings, and explain available defense options based on the evidence and court requirements.
